Requirement engineering is the most important phase within the software development phases since it is used to extract requirements from the customers which are used by the next phases for designing and implementation of the system. Because of its importance, this thesis focuses on the term aspect oriented requirement engineering, which is the first phase in aspect oriented software development used for the identification and representation of requirements gathered in the form of concerns. Besides the overall explanation of aspect oriented requirement engineering phase, detail attention is given to a specific activity within AORE phase called conflict resolution. Several techniques proposed for conflict resolution between aspects is discussed along with an attempt to give a new idea in the form of an extension of the already proposed model for conflict resolution. The need for extension to the already proposed model is justified by the use of a case study which is applied on both the models i.e. on the original model and on the extended model to compare the results.
